I don't think anyone but the person shooting the bow can properly tune it. I mean, he can do some tricks and work some magic to enhance performance, but the shooter ultimately has to tune the bow. The difference in grip alone would cause differences, and ......you're a leftie. He's not.

And if the secret is fewer strands........ummm, that I would be skeptical of. Apparently it works, but at what cost? String durability? I don't know, just thinking outloud.
